Speci'eation forming partof Letters Patent N 6,194, dated vMarch 20,1849.

Beit known that we, TILLY FLINT, of Westford, and VARREN FLINT, ofChelmsford, in the county of Middlesexl and State of Massaehnsetts, haveinvented e new and useful Improvement' in the Steelyarddalance forWeighingg and we dohereby declare that the saine is fully described and,represented in the 'following specification and accompanying drawings,letters, figures, and references thereof.

In the said drawings, Figure 1 represents an4 elevation o fone side'ofour improved-steelyardbalanee and its supportingframe., Fig. 2 is anelevation of the opposite'sideof the same. Fi gf is an end elevationio'fthe saine.

In the drawings, A denotes a .horiz'oi'ital metallic han supported onthe'top of a frame B in such mannera-s tob'e capable of being It has asteelyard or graduated. lever C suspended to it hy a stir.- rup c, as'seen Vin vthe drawings, the 'fulcraof the said steelyard being seen atao, Figs. l and 2. Directly above thesaid steelyard, and

a lever D, uihose:fulerun-journals are made tohang in a s tirrup d,suspended from the top bar of one side of. the frame l5, "lhesaid leverD carries on one arma sti rrup E, which is suspendedfrom it, -lreceivesthrough its has a scale-pan F depending'` fromits lower end, as seen inthe drawings. Apoise-weight G is screwed upon a screw 71, formed on: theother arm of the lever D, the said poise-weight being for the purpose ofbalancing'the weiggrht/f` of the scale-pan and its stirrup.

same side and on the long arm of the steek` yard is constructed so asterepresent the whole cosi of -the article whatever be its A On cach side,y Of the steelyard-lever there is a 'scale made;`

weight,.providedthe cost of said -woi ght comes within the limits of theScale.

Any article of which, either with orwithout aseertainingits weight, Wedesire to know the cost We place in the scalepan. This be ing done ,-Wenext lay hold of the slide-bar A, and. move the same longitudinally`until we bring thesteelyard into a convenient position to enable us toplace the stirrup of the scale-pan directly on that division of. theshort arm of the steelyard which denotes the price per pound or whatevermay be the base or stainlard of `weight. Having previously placed orhung amovable Weight l onv the long arm ol' the steell)'"ard, vWe movethe said Weight out on the saine .until we bring the steolyard into ahorizonf talposition. That division o t the scale of the said long-armon which the said wright may4 then be will denote the gross cost orwhole 'cost of the article in the scale-pan, it being understood thatthe proportions of the scales' on the ,long and short arms have beenpreviously properly regulated in such.ma-nner with' respect to the',balaneingaveight as to cause said weight to so indicate the wnole cosh'As the scales of `the steelyard are repre-v sented in 'Fig- 1, theyenable a -person to as-A certain the whole costof an y article, prbvidedlit does not exceed thesiunbf ;Iifty cents, for instance, and the priceper vpound does not exceed-twelve cents, for instance. The short scaleof thesteelyard 'is about one-half the length Ot thef long one.

divided into twelve parts, each of which is numbered `and subdividedinto eight parts, ties'anie being as seen in the figure. The

The said short scale long scale is divided Vinto one' hundred equalfjparts, numbered as seen in l"the drawings. Nowgit the poise Pweighstwo pounds, and .We place any article'in the scale the price of whichper pound is six eents,for instance, We next movefthe steelyard into aproperposition to enable ns to hang the scale or stirrup ber (i ot' thesca-le, denoting the price per pound. We next move the poise-weight P onthe other scale ,until the steelyard becomes horizontal. lf the poiserests on the division indicatedby 'the number l0,(Wll1ich would be 4thesixtieth on 1he'sea-le,) .the price oi? the whole article'would bethirtycents. TheOpposite side of the steelyard is divided in such manneras to enable us to ascertain thewhole .thereof on the division indicatedby the numprice of any articlewhen said 2 @nel price may be less thanoneV dollar, and the price of it per pound is less than twenty-fivecents. lr", however, We desire'to ascertain the Whole price of `anarticle Whose Weight would make the same exceed'one dollar and comebetween one and .two dol'la1"s,"wexnust apply a suitable Weight that is,such aone as would balance the steel- -Yard to the extent the Weight Pwould when placed attlie extreme end or 100 of the scale) onthesuspended platform l, hung at the end of the steelyard. Thisbeingdone, We can employ the poise P to determine the excess of priceaboye one-dollar;andbetween that and two dollars. l.

The scales and weights of the steelyard may be regulated in variousother proportions and s -Ways to produce the above effect, 'as will loe'readily understood by balaneemakersl 'The above -described ,apparatuswill be found especially useful to butchers, who by miean'sfof it willbe able to readily discover the whole sutnfto be paid for anypiece ofmeat without 'rendering-"it necessary to rst` aseertain its Weight yinpounds and fractions of pounds. By hanging the scale-pan 'on thedivision lO of the short arm of the steelyard, Fig, 2, the poise andscale on the saine side of the other arm maybe used to obtain ihe Weightof any article.

VThe combination We claim and consideras our invention, consists as'follows:

First, the steelyard and scale-pan or any equivalent or equivalentstherefor; second, the auxiliary ,scale on the short arm of thesteelyard; third, the movable bar A or its equivalent; fourth, thebalancing-lever vand stirrup of the scale-pan, the whole being made'-
